SRM PowerMeter Shimano 11-Speed

Di2 and 11 Speed Shimano Integration

Complete your dream bike-build with the industry standard in precision power measurement

The new SRM PowerMeter 11-Speed is the next generation of seamless drivetrain integration for Shimano groupo users and Power enthusiasts. Improving over the 7900 series SRM PowerMeter, the 11-Speed now boasts 3000 hours of battery life! Electronic shifting systems make gear changes faster and virtually eliminate missed shifts, but the forces on the chain rings are much higher than with mechanical derailleurs.

 

With this in mind Shimano developed new Dura-Ace 9000 chain rings which are 20% stiffer than previous rings. This not only benefits the shift, but also in power transfer from the crank arm through the spider and into the drivetrain. If you ride Shimano DuraAce 9000 mechanical or Di2 electronic, you will benefit from increased power transmission!

Available models: SRM-Shimano 11-Speed: 110mm BCD (53/39), (50/34), (52/36)

Experience

Powered by experience

Each SRM PowerMeter and PowerControl head-unit are made one at a time, by hand. Our production facilities are located in Julich, Germany and Colorado Springs USA. Every step of production is carried out by highly trained engineers and technicians who have a passion for quality craftsmanship.

Dependability

Dependability you can count on

A three-year global-warranty protects against defects and backs up your investments. Add on the industry's leading accuracy and data reception rate for a truly unrivaled power measurement device.

Race proven durability

Accuracy is everything

SRM uses a 144 point calibration protocol against a known mass measured to the exact gram. With exacting calibration and our auto-offset feature, the resulting power measurement of the SRM has error of less than 1%. The scientific community has been publishing peer reviewed research for over 20 years using the SRM PowerMeter as the bench mark for measuring power in physiological and human performance research studies. We don't claim anything, our accuracy is proven.

Scientifically Proven

Race proven durability

SRM's are designed to take whatever you can throw at them. From freezing temperatures, to boiling heat, SRM's are  designed to handle temperature compensation while maintaining accuracy with our "Auto" offset feature. Each SRM is designed to be sealed against water, snow, mud, sand, and cleaning solvents. SRM's are designed to work. Period.
